Specific embodiment

To further illustrate each embodiment, the present invention is provided with accompanying drawing.This little accompanying drawing is the invention discloses one of content Point, it can coordinate the associated description of description to explain the operation principles of embodiment mainly to illustrate embodiment.Coordinate ginseng These contents are examined, those of ordinary skill in the art will be understood that other possible embodiments and advantages of the present invention.In figure Component be not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.

" lens have positive refractive index (or negative refractive index) " described in this description, refers to the lens with Gauss light The refractive index on optical axis that theory is calculated is for just (or being negative).The image side surface, thing side are defined as imaging light and pass through Scope, wherein imaging light include chief ray (chief ray) Lc and rim ray (marginal ray) Lm, such as Fig. 1 Shown, I is for optical axis and this lens is radially symmetrical by axis of symmetry of optical axis I, and light is by the region on optical axis For optical axis near zone A, the region that rim ray passes through is circumference near zone C, additionally, the lens also include an extension E (i.e. circumference near zone C regions radially outward), with so that the lens group is loaded in an optical imaging lens, preferably into As light can't be by extension E, but the structure of extension E is not limited to this with shape, and below example is to ask Accompanying drawing succinctly eliminates the extension of part.In more detail, judge face shape or optical axis near zone, circumference near zone, Or the method for the scope in multiple regions is as follows：

As shown in figure 1, it is lens sectional view radially.From the point of view of with the sectional view, the model of aforementioned areas is being judged When enclosing, define a central point be on the lens surface with an intersection point of optical axis, and a transfer point is on the lens surface A bit, it is and vertical with optical axis by a tangent line of the point.If there are multiple transfer points radially outward, the first conversion is sequentially Point, the second transfer point, and away from the radially farthest transfer point of optical axis be N transfer points on effectively half effect footpath.Central point and first Scope between transfer point is optical axis near zone, and N transfer points region radially outward is circumference near zone, and centre can Different regions are distinguished according to each transfer point.Additionally, effective radius is hanging down on rim ray Lm and lens surface intersection to optical axis I Straight distance.

As shown in Fig. 2 it is with parallel through the light in the region (or light extension line) and light that the shape in the region is concavo-convex The intersection point of axle is determined (light focus decision procedure) in image side or thing side.For example, when light is behind the region, light Can focus on towards image side, with the Focus Club position of optical axis in image side, such as Fig. 2 R points, then the region is convex surface part.If conversely, light Behind certain region, light can dissipate, the focus of its extension line and optical axis M points in thing side, such as Fig. 2, then the region is Concave part, so central point is to being convex surface part between the first transfer point, the first transfer point region radially outward is concave part；By Fig. 2 understands that the transfer point is the separation that convex surface part turns concave part, therefore the definable region and the radially adjacent region Inner side region, with the transfer point be boundary have different face shapes.If in addition, the face shape judgement of optical axis near zone can According to the judgment mode of those of ordinary skill in the field, (refer to paraxial radius of curvature, be often referred to saturating in optical software with R values R values on mirror data base (lens data)) positive negative judgement is concavo-convex.For with thing side, when R values are timing, it is judged to convex surface Portion, when R values are to bear, is judged to concave part；For with image side surface, when R values are timing, it is judged to concave part, when R values are negative When, it is judged to convex surface part, it is concavo-convex identical with light focus decision procedure that the method is determined.

If without transfer point on the lens surface, the optical axis near zone is defined as the 0～50% of effective radius, near circumference Region is defined as the 50～100% of effective radius.

Fig. 3 is that the lens image side surface of the first example only has the first transfer point on effective radius, then the firstth area is light Axle near zone, the secondth area is circumference near zone.The R values of this lens image side surface judge that optical axis near zone has for just One concave part；The face shape of circumference near zone is different with the inside region radially close to the region.That is, circumference near zone and The face shape of optical axis near zone is different；The circumference near zone has a convex surface part.

Fig. 4 is that the lens thing side surface of the second example has first and second transfer point on effective radius, then the firstth area For optical axis near zone, the 3rd area is circumference near zone.The R values of this lens thing side judge optical axis near zone for just For convex surface part；Region (the secondth area) between the first transfer point and the second transfer point has a concave part, circumference near zone the (the 3rd Area) there is a convex surface part.

Fig. 5 be the 3rd example lens thing side surface on effective radius without transfer point, now with effective radius 0%～ 50% is optical axis near zone, and 50%～100% is circumference near zone.Because the R values of optical axis near zone are just, so thing Side has a convex surface part in optical axis near zone；And without transfer point between circumference near zone and optical axis near zone, therefore circumference Near zone has a convex surface part.

The optical imaging lens of the present invention, are a tight shots, and are by sequentially arranging along an optical axis from thing side to image side An aperture, one first lens, one second lens, one the 3rd lens, one the 4th lens, one the 5th lens and one the 6th lens institute Constitute, each lens all have a refractive index, and towards thing side and the thing side and a direction that imaging light passes through is made with one Image side and make the image side surface that imaging light passes through.The optical imaging lens of the present invention have refractive index for only aforementioned six altogether Lens, by designing the detail characteristic of each lens, and can provide shorter optical imaging lens length and good optical property.

The positive refractive index of the first lens can provide the positive refractive index needed for camera lens entirety, and the negative refractive index of the second lens can be repaiied Positive optical system overall aberration, optical axis position is designed at the thing side of the first lens and can help to improve image quality and shortening mirror Head entire length.

The optical axis near zone of the thing side of the first lens and the convex surface part of circumference near zone can assist to receive Integrated Light As light, the positive refractive index that the positive refractive index of the 4th lens and the 5th lens can be needed for sharing system entirety.The thing of the second lens Side is in the concave part of circumference near zone, the image side surface of the 3rd lens in the convex surface part of circumference near zone, the 5th lens Image side surface in the convex surface part of circumference near zone and the image side surface of the 6th lens in the convex surface part of circumference near zone, can phase Mutually collocation so that the overall image quality of optical system improves, shortens the overall length of camera lens, drops nearly f-number and reach expansion The effect of big shooting angle.
